The Shimano 105 ST-R7020-L brings the all-condition confidence of hydraulic disc braking together with crisp, intuitive 11-speed shifting in a single left-hand lever. Purpose-built for road riders who want reliable, high-performing components without stepping into Ultegra or Dura-Ace territory, this Dual Control Lever delivers consistent hydraulic modulation and front-shift precision every ride.

Highlights

  • Hydraulic disc brake actuation: Shimano mineral oil hydraulic system delivers powerful, progressive braking with excellent feel in all weather conditions.
  • Dual Control shifting: Integrated brake and shift lever design enables effortless one-finger front shifting while maintaining a clean cockpit.
  • Extended reach adjustment: Up to 15 mm of reach adjustment via bolt allows riders of all hand sizes to dial in the perfect lever position.
  • Revised shift unit: Updated internals borrowed from Shimano MTB technology deliver fast, positive front shifts with minimal effort.
  • Ergonomic hood shape: Reduced hydraulic interior volume creates a balanced, comfortable hood profile whether riding in the drops or on the hoods.
  • Optislick inner cable: Included Optislick-coated inner cable reduces friction for smooth, consistent shifts over the long term.

Construction

The ST-R7020-L features an aluminium brake lever blade paired with a composite lever body and steel clamp, keeping weight in check while maintaining durability where it counts. The straight-port SM-BH90 hose connection (JK-SSR or J-SSR) integrates cleanly into the lever body, and M7 funnel venting simplifies brake bleeding for workshop servicing.
